Episode 1
Our cameras follow the engineers, technicians and train staff who are under pressure to complete their section of the project, including building and fitting out 10 brand new stations, learning to drive the new fleet of trains, and testing the 21-km twin tunnels beneath London, in a bid to make it safe for the public.
The episode ends with the shock news that the team fail to complete the Elizabeth Line on time. With the delay costing almost three million pounds a day, every hour is critical in the race to launch the railway.
